Addressable Digital Potentiometer

General Description

Features

The DS1805 addressable digital potentiometer contains

a single 256-position digitally controlled potentiometer.

Device control is achieved through a 2-wire serial inter-

face. Device addressing is provided through three

address inputs that allow up to eight devices on a sin-

gle 2-wire bus. The exact wiper position of the poten-

tiometer can be written or read. The DS1805 is

available in 16-pin SO and 14-pin TSSOP packages.

The device is available in three standard resistance val-

ues: 10kΩ, 50kΩ, and 100kΩ. The DS1805 is specified

over the industrial temperature range. The DS1805

provides a low-cost alternative for designs based on

the DS1803, but require only a single potentiometer.
